Closure



FIG. 1 is a perspective view of the closure.

FIG. 2 is a top plan view of the closure, the bottom of the closure being without ornamentation and forming no part of the claimed design; and,

FIG. 3 is a front elevational view of the closure, the back and side elevational views being identical thereto. 

I claim the ornamental design for a closure, as shown and described.
